Anti-fog products dissipate moisture, helping it evaporate. They are for use on the inside of a windshield.

Apply window treatment products with a terry cloth or microfiber towel. Spray the towel rather than the surface and wipe it evenly across the glass. Remove excess fluid with a clean, dry cloth to eliminate haze.

Avoid getting window treatment products on rubber surfaces. They contain alcohol, which can cause rubber to dry or crack.
